Question

13) The diameter of a plant cell is 1.26 m and the length of a bacterium is 5.1 m. Compare their diameters.

Answer 1

The diameter of the bacterium is 4.05 times the diameter of the plant cell

Explanation:

Given

The given parameters both represent diameters

Plant Cell; P = 1.26m

Bacterium; B = 5.1m

Required

Compare both diameters;

Write out both expressions

`P = 1.26`

`B = 5.1`

Divide B by P

`(B)/(P) = (5.1)/(1.26)`

`(B)/(P) = 4.04761904762`

Approximate

`(B)/(P) = 4.05`

Multiply both sides by P

`P * (B)/(P) = 4.05 * P`

`B = 4.05 * P`

`B = 4.05P`

This implies that;

The diameter of the bacterium is 4.05 times the diameter of the plant cell
